Description
Technical field
The present invention relates to the field, insertion section of video laryngoscope and video laryngoscope.
Background of invention
Laryngoscope is the armarium generally used in oral cavity and trachea medical procedure, it can be used to the view obtaining glottis or larynx, or handle tongue, glottis or larynx so that insert endotracheal tube or other devices (as endoscope), they can be equipments separately or can be incorporated into laryngoscope.
Laryngoscope comprises insertion section, and they are the laryngoscope elongate portion extending into the oral cavity of experimenter at intubation.Insertion section be attached to removedly laryngoscope body or as laryngoscope integration portion or itself serve as laryngoscope.Except insertion section, laryngoscope generally includes handle, handle normally elongated and be arranged to and insertion section near-end at an angle or and the near-end of insertion section is almost parallel or any angle between them.Insertion section and handle can be integrally formed.
Video laryngoscope comprises the imaging device in insertion section.Imaging device is camera normally, but can be extend to the optical transmission device (such as, one or more fiber optic cables) not being in the camera (such as, in use remained in the extrabuccal handle of experimenter) in insertion section.Imaging device can be a part for insertion section, but the part that imaging device is the main body of laryngoscope is also known, such as, be installed to the insertion section holding element keeping removably insertable portion.The example of such equipment is shown in EP1638451 (McGrath).Such equipment is favourable in the following areas: removably insertable portion can be disposable and imaging device can be protected from humoral pollution, thus allows imaging device to be reused.Insertion section holding element can be also fastening element, thus provides mechanical strength to insertion section.Video laryngoscope can have to be integrated screen or sends image to remote display by wired or wireless interface.
Before exploitation video laryngoscope, intubate uses autoscopy to perform usually.In autoscopy, intubationist seeks the direct sight line view of the larynx obtaining experimenter.Some known insertion sections of laryngoscope are straight substantially, as Miller or Wisconsin blade.But the blade of insertion section is more bending with the larynx of oropharynx towards them entering experimenter better.Such as, the most common curvature of insertion section is commonly called Macintosh curve.Curvature is relatively gentle and when being inserted into the oral cavity of experimenter, the blade bent is used to lift and handles the tissue (as tongue) in oral cavity in sight line outward gentlely, to allow intubationist to the direct view of the larynx of experimenter.
But video laryngoscope allows the view obtaining the larynx of experimenter from the imaging device of (and being therefore in use in the oral cavity of experimenter) in insertion section, and need not lift significantly or handle tongue.This allows the direct view obtaining larynx.Some video laryngoscope insertion sections have significantly very shallow curvature to allow to obtain direct view.In this case, the ability obtaining the view of larynx before intubate is helpful but dispensable.
But, when there is foreign body in the oral cavity of experimenter, or when effective view of larynx can not be reached with direct view blade, as when the head of experimenter and cervical region can not move the direct sight line obtaining larynx, the insertion section with more deep camber usually must be used to be inserted into oral cavity to allow blade.In this case, intubationist uses video laryngoscope camera and screen indirectly to carry out visual to larynx.Indirect view insertion section is called as in this article for the insertion section when user normally can not obtain the direct sight line of larynx.
Aspects more of the present invention solve provides the insertion section of suitable shape to promote the technical problem of the intubate of video laryngoscope, is especially relevant to the intubate of different air flue.For user, the especially rawness user of video laryngoscope, was absorbed in before starting to insert endotracheal tube that to obtain most probable view from the camera of video laryngoscope not uncommon.In doing so, they usually must be excessively dark in the oral cavity interpolation of experimenter by the end of insertion section, thus directly lift epiglottis.This usually composition lack sufficient space endotracheal tube imported trachea because with the end in insertion section by correctly complete compared with in paddy, the end of insertion section is too forward and lift epiglottis in the mouth of experimenter.This can cause user to apply unnecessary power to attempt to vacate more spaces to import conduit or catheter positioning to be obtained more forward.The incorrect location of blade in paddy can cause the situation being called " soft epiglottis " (misnomer that user uses when epiglottis is in the sight line of vocal cords), does not usually suitably lift epiglottis its emersion sight line to be caused by insertion section.
J-shaped insertion section is substantially provided to be known, the bending or elbow having straight proximal region, straight distal region and limit therebetween.Equally, the known insertion section providing the blade of the mixing with band bending portion and straight portion, the angle wherein between these parts or curvature have sensitive change (as McGrath series 5, Glidescope and Belscope).Such insertion section can provide the reasonable view of larynx, but is difficult to insert.Aspects more of the present invention are sought to improve the shape of insertion section so that be inserted into experimenter, allow the good view obtaining larynx simultaneously.Minimize the distortion of tissue, avoid using excessive power and avoiding the anatomical excessive friction of experimenter to be preferred.
The shape of the lower surface of some solution insertion sections, aspect, because this surface contacts the tongue of patient during inserting.The shape of some solution insertion section, aspect entirety, so that intubate.
Aspects more of the present invention are sought to solve user and are inserted insertion section in experimenter's mouth and cross deeply or problem dark not.Propose and provide single marking on the upper surface of laryngoscope insertion section, the dividing line between the typical insertion depth of instruction adult and the typical insertion depth of child.But this is not gratifying, because the correct insertion depth of insertion section exists significant change between each experimenter organized, and so single indicatrix is not of practical assistance.
Some embodiments of the present invention solve the technical problem that the friction between insertion section and the tissue of experimenter causes.Friction between insertion section and tissue can cause and damages and affect the safety of intubate.Such as, the lip of experimenter may adhere to insertion section and be pulled on front tooth, thus cause damage and hemorrhage.
When using indirect view laryngoscope (as video laryngoscope) to experimenter's intubate, the user using the direct view Macintosh laryngoscope of tradition to train may by endotracheal tube inserting error path.During the direct view laryngoscopy of tradition, endotracheal tube is through the upper surface in oral cavity.But, during indirect laryngoscopy, make endotracheal tube be more suitable near insertion section itself.Have in the insertion section compared with steep curve, optimal is that endotracheal tube is near the summit running through the curve of the zone line of the insertion section in oral cavity.Aspect more of the present invention solves user inserts endotracheal tube problem along the path (but this is unsuitable for video laryngoscope) being suitable for traditional Macintosh laryngoscope, and has the insertion section of steep curve more specifically.

Bending area may extend into the near-end of the lower surface of insertion section.Bending area may extend into the far-end of the lower surface of insertion section.Observation panel can in the zone line of insertion section.But in certain embodiments, distal region can extend to the distal end of insertion section from observation panel.
Bending area extends to the bead of the far-end of the far-end of the lower surface of insertion section or the lower surface of insertion section usually.
Situation can be the minima (maximum of longitudinal curvature) that the bending area of lower surface has longitudinal radius in the zone line of insertion section.
Situation can be the minima place of longitudinal radius in the zone line of insertion section, the longitudinal radius of bending area is less than the longitudinal radius at any some place of the bending area in proximal region and distal region (and therefore the longitudinal curvature at the maximum place of longitudinal curvature is greater than the longitudinal curvature at any some place of the bending area in proximal region and distal region).
Situation can be the longitudinal radius consecutive variations in the middle region of lower surface.
Preferably, more than the lower surface of the insertion section far-end 90-degree bent from the near-end of insertion section to insertion section, and bending more than 96 °, more than 98 ° or more than 99 ° usually.
Situation can be 75% (or be not less than 85% or be not less than 90%) that the longitudinal radius of lower surface in zone line is not less than the minimum profile curvature radius of the lower surface in proximal bend region.
By avoiding the excessive longitudinal curvature in zone line, insertion section is easy to import experimenter.This is formed with the insertion section in lower surface with discontinuous angle (or elbow) and contrasts.
Therefore insertion section can roll into patient, and without the need to controlling anatomy.
Situation can be the longitudinal radius (and therefore curvature) of bending area is constant in proximal region.
Situation can be the longitudinal radius (and therefore curvature) of bending area is constant at distal region.
Also find, use the insertion section with following lower surface especially favourable: this lower surface has the first constant bending region (proximal region in insertion section) of the constant longitudinal radius of band and the second constant bending region (distal region in insertion section) of the constant longitudinal radius of band, together with the zone line with variable longitudinal radius (it is less than the longitudinal radius in the first or second constant bending region usually) therebetween.Be compared with the insertion section (thus needing the bending of more restrictions or elbow) of straight lower surface with having along its most of length, the shape of gained is easier to insert.
Usually, the longitudinal radius of the bending area of lower surface has minima in the middle region and the longitudinal radius of the bending area of lower surface is increased at least 150% or 175% of the longitudinal radius of the bending area at the minima place at described longitudinal radius, or is preferably increased at least 200%.(minima of longitudinal radius is the maximum of curvature).

Situation can be the minimum longitudinal radius of bending area in zone line be greater than the minimum longitudinal radius of the bending area in proximal region 75% (and be preferably more than 80%, be greater than 85% or be more preferably greater than 90%).
When bending area has constant curvature in proximal region, the minimum longitudinal radius of the bending area in proximal region will be the longitudinal radius of bending area in proximal region.
Therefore, the maximum longitudinal radius of the zone line of insertion section is less than (and therefore the minima of longitudinal radius is greater than) and in use has longitudinal radius in the known laryngoscope insertion section of height bending area in oropharynx or elbow.
Camera is positioned at the position similar to insertion section, and wherein angle or curvature have slight change, but does not have awkward angle in insertion section.This is reached by the insertion section with uniqueness crooked outline, and this uniqueness crooked outline has variable radius of curvature serves at zone line, and this variable radius of curvature serves seamlessly enters the constant curvature radius of proximal region.This present situation means the bending lower in the oral cavity of mid portion in use in conjunction with fine rule shape profile, and therefore the tissue of experimenter needs less power just the end of blade can be placed in paddy, and camera is therefore at optimal location, to obtain enough preceding view from camera, also allow sufficient space for endotracheal tube through vocal cords simultaneously.This helps to overcome the known difficulty of placing and having the conduit of the blade of sharp sweep.

The detailed description of exemplary embodiment
Referring to figs. 1 to 2, the elongated insertion section 4 that video laryngoscope 1 comprises handle 2 and extends from handle.Handle has the display 6 for illustrating the video image using the light cause camera 8 obtained from LED light source 10 to obtain.Camera is positioned at the first half of insertion section.Insertion section has far-end 12 and relative near-end 14.Insertion section has in use towards lower surface 16 and the relative upper surface 18 of the tongue of experimenter.Elongated member 34 is proximally longitudinal extension along insertion section, and flange 36 is laterally extended from elongated member, and limits the lower surface of insertion section together with the lower surface of elongated member.
With reference to figure 2, handle has the elongated insertion section holding member 22 therefrom extended, and insertion section has the elongated passageway 24 entering elongated member from the proximal extension of insertion section.Insertion section is formed by transparent plastic material and comprises serves as observation panel and it has for redirecting light to reduce light scattering and light to be directed to the window 32 of one or more prisms of camera from required direction.Insertion section holding member is formed by rustless steel and keeps camera 8 and light source 10 and for receiving image for display electric wire (not shown) on a monitor to camera and light source power supply.Elongated insertion section holding member also serves as reinforced element, thus resists buckling and thus provide mechanical support to insertion section.Therefore, camera to be in insertion section but an and part for non-insert.It is connected to handle by insertion section holding member and collects image by window.
But in certain embodiments, handle and insertion section combine formation.In certain embodiments, camera is a part for insertion section.
With reference to figure 3A to 3G, insertion section has proximal region 26, the distal region 28 extending to far-end and the zone line 30 between them that in use described insertion section extends between the tooth of experimenter.First flange 36 (such as shown in Fig. 3 E and 4) transversely extending and leave observation panel and limit the part of the lower surface of insertion section at elongated member.Another flange 38 (upper surface close to elongated member) on the cross side relative with the first flange extends from the transverse wall 20 of elongated member, and provides additional mechanical to support.
Bead 40 provides at the far-end of insertion section, and with the tongue helping the end of insertion section to slip over experimenter, and insertion section keeps in use dismantling by laryngoscope handle by the clip 42 of proximal end.
Fig. 5 illustrates the shape of the lower surface of insertion section.Can see, the lower surface continuous bend in the vertical of insertion section, at least from its position of passing through between the tooth of experimenter in use to the bead of distal end.The part 44 of this continuous bend serves as sweep.But curvature is also non-constant and show the numerical value of the longitudinal radius of the length along insertion section for particular example embodiment.In proximal region, there is constant curvature radius (being 65.5mm in this example).Distad be in progress along insertion section, curvature increases (and therefore radius of curvature (it reduces when curvature increases) is down to about 60mm) at zone line subsequently, and curvature distally reduces (and therefore radius of curvature is increased to about 135mm) again, makes the longitudinal curvature of sweep in distal region be less than the longitudinal curvature in proximal region.
Therefore, longitudinal curvature is constant in proximal region.Also there is (relatively short) constant curvature region near distal end, and variable longitudinal curvature portion is between these two constant bending sections.
Find that this contour curvature means when insertion section is positioned correctly, the end of insertion section is in paddy, compared with traditional Macintosh insertion section, bending of insertion section is located lower in mouth in use, and result relates to less tissue manipulation, but still follow the anatomy of experimenter.When blade is used correctly, when optimum insertion depth in the mouth entering experimenter, compared with other modes, the user of laryngoscope needs less power just can lift epiglottis to obtain the view of vocal cords.
Flange 20 does not extend to the near-end of insertion section, but 20% of length with the spaced apart about insertion section of near-end.This makes the pressure tongue portion of insertion section very very thin.This and significantly steep curve and constant altitude (being less than the width at the narrowest part place of insertion section) are coupled, and cause the blade solving following problem: optimize from camera enough before view and also allow sufficient space to pass through vocal cords for endotracheal tube simultaneously.
Fig. 5 and Fig. 6 A to 6C illustrates according to the example with the insertion section of each size of the present invention.Example shown is for the experimenter for needing No. 4 endotracheal tubes.Experimenter for different building shape changes by shape.This is indirect view insertion section and can sees from Fig. 6 B, the lower surface of insertion section bending 99.2 ° between the proximal and distal ends.With reference to figure 6A, the ultimate range between the lower surface of insertion section is 29.3mm, and this is that the near-end of the lower surface of insertion section and far-end are increased to air line distance (112.3mm, as shown in Figure 6 C) 26.1%.The insertion section that these features instruction relative altitude is bending, for the indirect view of acquisition, is applicable to different air flue.
Fig. 7 A is view (the detachable blade of dB5 of the transverse direction from known laryngoscope insertion section 80, can buy from the AircraftMedical company limited of Edinburgh, Britain), it have be with the proximal region 82 of constant curved lower surfaces 84, have the distal region 86 of straight lower surface 88 and therebetween discontinuous bending 90.

Fig. 7 C is the view of the horizontal direction from traditional Macintosh laryngoscope that can extensively obtain with direct view insertion section 110.
Fig. 7 D is the view of the horizontal direction from laryngoscope insertion section according to the present invention.
Fig. 7 E illustrates the insertion section with the insertion section of Fig. 7 A being coated with dotted line of the present invention.Can see, laryngoscope of the present invention is more bending, but lower surface does not have discontinuous bending, thus makes insertion section be easier to insert.
Fig. 7 F illustrates the insertion section with the insertion section of Fig. 7 B being coated with dotted line of the present invention.Can see, laryngoscope of the present invention is more bending in the vertical, and longitudinal curvature that can be variable, and the better indirect view of trachea is provided, keep the benefit with the lower surface of continuous bend in the vertical simultaneously, thus make to be easy to insert and do not have experimenter to damage.
Fig. 7 G illustrates the insertion section with traditional Macintosh insertion section of Fig. 7 C being coated with dotted line of the present invention.Can see, laryngoscope of the present invention is more bending, thus during the airway intubation of difficulty, provide better angle to carry out indirect observation larynx.
Fig. 8 and 9 is the cross sections of the experimenter by experience with the laryngoscope tracheal intubation according to insertion section of the present invention.Because insertion section extends around palette 52, so the good view of trachea 56 can be obtained from camera.But in fig. 8, insertion section is not properly inserted into.The far-end of insertion section limits the access of endotracheal tube to trachea.In fig .9, insertion section is properly inserted into.When obtaining the optimal view of larynx, be inserted into experimenter in insertion section when crossing dark, the user being unfamiliar with video laryngoscope may by mistake make a mistake, as shown in Figure 8.
The shape of insertion section, especially constant bending lower surface, has a little more greatly but not excessive curvature at zone line, provides the insertion section that easily can roll into patient, and controls the anatomy of patient without the need to user.When proximal region does not have curvature, be necessary to provide overbending, this oneself shows usually in camera area.
With reference to figure 10A and 10B, the upper surface of insertion section provides longitudinal scale, formed by multiple labelling 70, they are evenly spaced apart in the vertical.In this example, labelling is the numeral of spaced apart 1cm, and each numeral is the measurement of the distance of the far-end of upper surface from labelling to insertion section along insertion section.
Labelling enable user by reference to labelling relative to the position of upper (jaw) front tooth of experimenter to assess the insertion depth of insertion section.This enables user determine optimum insertion depth, and for using the best techniques of the video laryngoscope with insertion section.
Can for the absolute value of particular subject record insertion depth.The insertion depth adopted in particular procedure can be stored, to provide the record of this process.Optimum insertion depth can be scheduled, such as, from the table of the proper placement depth of the given build for experimenter or from the measurement of experimenter.
Labelling can use at intubation with the excessive insertion avoiding insertion section, as shown in Figure 8.Labelling also can be used to the relative adjustment making insertion depth, such as, can obtain optimal view, and preset distance (such as, 1cm) usage flag can be retracted to judge displacement relative to the maxillodental position of experimenter in insertion section by user subsequently.
With reference to figure 10A, 10C and 11, vision highlights 60 and provides on the upper surface of flange 36.Vision highlight for indicate to user they should by endotracheal tube along closely or the upper surface of engagement flange path insert.Vision highlights one or more that can comprise and point in the arrow of distal direction, the picture of endotracheal tube and text.Vision highlights the contact area that endotracheal tube can be indicated should to contact during inserting.Vision highlights can by molding.Vision highlights and can be printed.Vision highlights and can be etched.It can be the image embedded that vision highlights, such as, between shaping period, (such as, use double injection mould).
With reference to Figure 12, the transverse wall of insertion section has the elongate guide line 65 being adjacent to the optimal path of the trachea for endotracheal tube being inserted experimenter's (insertion section will be imported into this experimenter) extend in the vertical.Guide line can be such as ridge or image, and conduit inserts along optimal route by assisted user.
Import the optimal route of endotracheal tube usually near the buckling of the upper surface of the flange adjacent with observation panel.Optimal route for importing can be the most direct route of endotracheal tube, usually includes the inherent curvature of endotracheal tube in consideration.Optimal route may need the minimum bending of endotracheal tube.
In certain embodiments, insertion section comprise be positioned at insertion section lower surface and upper surface on one or more surf zones coarse under the microscope.Surface portion coarse under the microscope can obtain by grinding by the veining of the correspondence of the mould for the formation of insertion section or such as.
Compared with being completely level and smooth situation with surface, surface portion coarse under the microscope presents the lower contact area with skin, thus reduces friction.This has and reduces effect to the risk of the damage of lip, otherwise during use lip may being drawn to experimenter tooth on and hurt by tooth.
Areas scatter light coarse under the microscope and therefore give insertion section frosted appearance.But surf zone coarse does not under the microscope have extend through observation panel, at this, they will block camera.In these embodiments, lower surface and upper surface do not have an insertion section of surf zone coarse under the microscope on observation panel, can mainly (and complete in certain embodiments) be made up of the transparent plastic of single molding.
Further change and amendment fall in scope of the present invention disclosed herein.
